"They are different, aside from being located at different elevations, the east diving board connects the ground entrance with B1M level that connects to the N/W lines, while the west diving board -being located at a lower elevation- connects ground entrance with B1 balcony level. Design or arrangement of the form is the same."

Thanks Otie. They looked different in the renderings, but look similar now that they are erected.

I finally found the needed sources to get started, but I don't have time to get started yet. I would first like to give a big thanks to 325ccr for his great photographs that will be a crucial aid due to the lack of detail of the PDF I found.

On the topic of actual construction, all that's left of the M760D is the red sliding base.

each boom extension piece is 30.6 x 10.5 x 12.3 feet and weighs in at 7909 pounds. Hope that makes a good reference when the pieces of the hub come.

Otie also told us that the plan is to have another 1280 on the west side, and a crawler for the rafters.

Yep, two M1280d. And after the portals are installed the tower cranes will be removed and the crawler will finish the hub. Methinks that the reason they are frantically working on the street grid over the site is to allow a constant flow of truck traffic without having to back up at any time. The whole 120 foot long section piece thing seems a bit far out there, literally. I don't know how they'll be able to turn into the site with a trailer, or get there in the first place. unless there are one or two 27 x 120 foot pieces that will be moved using one of those rolling bed deals like they move houses on.

I guess no one here knows what the two "Lego pieces" are. Judging by the height of the two manhole cylinders next to the north one, it appears they will be (mostly) buried. So they are probably for some sort of utilities.

With the West side crane now gone, this may be the last best view of inside the Oculus we'll ever have.

I've been thinking about them too. Maybe they could they be underground vaults that will store the equipment for powering and controlling traffic signals at the intersection of Greenwich and Fulton and the intersection of the pedestrian Cortland Way and Greenwich [hope I remembered the street names right]. I don't remember seeing the above ground boxes normally at or near a signaled intersection in any of the renders.

I doubt that. Traffic lights don't need a huge vault like that, usually the controls are in a 2-foot-square (if even that) box that is bolted to one of the poles.

These things are huge, probably about 10' x 20'. And they are each positioned directly over a large rectangular opening in the concrete deck below. Maybe they are for major electrical or telecom connections or something like that.

Glad that you find them use full! I want to make another trip down there in the sun light to get some more.

They were working all through the night last night (Sunday) with the AC500 to get the Oculus cleared. Today it looks clean down there, seems like they don't want to waste any time.

And also to give a heads up once things get rolling down there I would like to get some over head photos from the Millenium Hilton across the street like I did when the 18000 was there.

Are the going to use the AC-500 to put up the second Favco or can the first one reach over that far?

I'm pretty sure they'll need the AC500, the 1280 cannot reach that far. But they'll need to remove the whole jib extension just to move the crane a few meters away, because I don't think the AC500 can erect it in its current position.

It will be interesting to see if they move the AC500 more west. Seems like a lot of work just to move a few feet. He did take the 760 down right where is now though so only time will tell.
